impressed her classmates. Meanwhile, Jenny (Taylor Momsen) has been hanging around New York City with one of Chuck's (Ed Westwick) clients, international drug dealer Damien Dalgaard (Kevin Zegers).

Production The episode marks Hilary Duff's final appearance in the role as Olivia Burke after fulfilling the whole contract as a recurring character for the third season. Recording artist Lady Gaga makes a cameo appearance. Fashion Similar to most Gossip Girl episodes, "The Last Days of Disco Stick" drew heavily on fashion. Costume designer Eric Daman dressed Leighton Meester in a Theory coat, Vince leggings, a Chanel bag, Ralph Lauren hat and Manolo Blahniks. When styling Blair's more mature look, Daman stated, "I chose very sleek, very linear clothing...It's almost architectural in design." Daman drew on the character of Jenny, citing her preference for wearing "lots of vintage clothes like torn-up jeans and paint-splattered T-shirts." and dressed Momsen in an Alexander Wang jacket over a Topshop dress and Hue tights. Daman also cited musician Courtney Love as an inspiration for the character's style. When dressing Blake Lively, Daman considered Serena's confusion over her feelings for the married congressman and incorporated her character's outfit into the episode. "From a fashion standpoint, Serena is in a little bit of an identity crisis", Daman explained. InStyle praised her Serena in her Twenty8Twelve coat, Alice and Olivia dress, Hue tights, a Kotur bag, Stephen Dweck necklace and Manolo Blahniks, describing it as "perfectly put-together". Eric Daman praised Vanessa's growing confidence, commenting "She's becoming her own woman", and accessorized Vanessa's Diane von Fürstenberg coat and Nanette Lepore dress with American Apparel leggings, a L.A.M.B. bag and a bold blue Gemma Redux necklace. Reception "The Last Days of Disco Stick" was watched by 2.24 million viewers. The episode received mixed reviews. Isabelle Carreau of TV Squad felt that the episode was very predictable, and that even though "the drama following the threesome was put center stage, yet it fell flat".
